1'0 all whom. it "my I'UIII'I'I'II.

Be it known that we, Gannon l}. (onco- RAN and (ii-zones A. Donma, citizens ol the United States, residing at St. Louis, Missouri, have jointly invented a eertain new and usefnl lmprovi-nn-intin Needle and Shuttle Guards for Sewia -Machines, of which the following is a hill, car, and exact description, such as will enable others skilled in the art to which itap ertains to make and use the same,

oing bad to the accompanying drawings, forming part of this specification, in which- Fi 'urc l is a side elevational view. Fig. 2 is a iront clevational view of the machine, sbowin our invention a plied. Fig. 3 is a vertical sectional view t n'ongh the shuttle mechanism and the guard. Fig. 4 is a fragmentary clevational view of a portion of the shuttle mechanism, and Fi 5 is a cross-sectional view on the line 5 5 0 Fig. 2.

This invention relates to sewing-machines, and we have herein shown our invention as embodied in a machine of the type shown in our Patent No. 760,732, granted May 24, 1904.

One of the objects of the invention is to provide a sewing-machine with a guard for roventing the work being operated on from eing engaged by an upwardly-moving workpenctratmg member or by the shuttle.

Another object of the invention is to pro. vide a novel guide for a work-penetrating member which will prevent the portion of the vamp adjacent to the welt of the shoe being operated on from being accidentally penctrated by said member; and still another object is to rovide means for retaining heat in the shutt eraee and also holding the bobbinrctainer in operative position.

Referring to the drawings, 1 designates a stand or framerarrying the shuttle and the part in which the needlebar is mounted, the

sieedle on said bar when in its operative position being adjacent to the shuttle, as shown In Fig. 3. The shuttle is mcloscd in a recess 2 in the frame, and said shuttle and. needle are inelosed by a door 3, that is hinged to the frame 1 and is secured in place by a catch 4. Adjustably secured to a mrtion of the frame of the machine is a wor -table 7, provided with a ncedle'guide 8, having a passageway in clinement with the needle, as shown in Fig. 3. Projecting outwardly from the outer end of said guide is a lip that affords an extended marin -surface for the welt of the shoe, and said guide is extended downwardly, as shown in Fig. 2, to form a face, which is engaged by the portion of the vamp adjacent to the outer sole of the shoe, said face cooperat ing with the door 3 to prevent any portion of the shoe being operated on from moving accidentally into the ath of the vertical reciprocating needle, t c upper edge of the door bein provided with a cutflout portion in which-t no lower end of the guide 8 rests.

The door is provided with a s ring 9, which is movable with the door and avmg a free end which bears against the bobbin-holder and while )crmitting it to rotate prevents accidental isplaccment of either the shuttle or the bobbin-holder. Pro'ecting inwardly from the door and integral t crewith is a. log or projection 10, which is adapted to engage the projection 11 on the bobbin-holder, so that said bobbin-holder will be prevented from rotating when the shuttle rotates, and thus obviate the liability ofthe shuttleholder interfering with the needle during the operatiop of the machine. 12 designates a. hot-water or steam flue in the frame and beneath the recess for the=.huttle mechanism said flue being adapted to receive a suitable fluid to heat the shuttle-recess, the heat being retained within the recess by the ahove-described door.

'Althou h our invention is herein shown as embodied in a guard for preventing the work being operated on from being accidentally engaged by an upwardly-moving needle, it is obvious that it could be used equally well for preventing the work from being accidentally en aged b an owl in a machine in which the aw move upward] to enetrate the work. and wherever wchavd so the term work-penotratiiw member in the claims we mean either an aw or a needle.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. In a machine of the class described, the combination with a frame having a lateral )rojection containin a shuttle-recess and raving a heat-{hie below the same, a door for closing the 0 on side of said recess to prevent the escape oi heat therefrom. said door having yielding means for maintaining the shuttie in operative position within the recess of described, the combination, with the shuttlesaid frame and being provided with aprojechead, a shuttle therein, of a guard-cap or tion for engaging a portion of the bobbin-car- 4. In a sewing-machine of the character shield arran'ed on said head to'cover and 35 5 rier to prevent rotation thereof; substantially protect the s uttle and its coacting parts, a

as described.

2. In a machine of the class described, a wrk-table, a reciprocating work-penetrating member ada ted to move upwar iv to pene- IO trate the wor and a guide having a passageway in alinement with said work-penetrating member, said guide having a work-engaging surface at approximately a right angle to the plane of the workable; substantially as do scribed,

3. In a machine of the class described. a frame, a work-table mounted on said frame, a workenetrating member located lJ'Il V i'said tab e and moving upwardly to pfllivliatv l i l 4 the work lyin thereon, a guide fastened to the table and provided with an opening through which said work-penetrating memmber moves, said guide also being rovided with a downwardly-projeeting guar ing portion, and a door carried by the frame and co- U operating with the guarding portion on said 7 guide to form an inc osed passa e-way which prevents any portion of the wor being operated on from moving e eidentally into the 39 path of movement of said work-penetrating member; substantially a s described.

bobbin-case provided with a horn, means arranged on said guard-cap .to enga e said horn and a spring-arm to engage the obbin- Case. 4o

5. In a sewing-machine of the character described, the combination, with the shuttlchead, a shuttle therein, a bobbin-case provided with a horn, a needle-bar and a needle,

a guard-cap or shield hingedly connected i\. said shuttle-head and adapted to be swun i ate engagement with said head to cover an rotect said shuttle, needle-bar and needle, a iatch to hold said uard-cap in closed posi- 1 ion, a guide rib or ange formed on the inner side of said cap, and a s ring-arm carried by the cap to engage and old the bobbin-case in place, n testimony whereof we nereunto afim our signatures, in the presence of two witnesses, this 3d day of July, 1905.
